'This invention relates to limprovements in lifting tools and especially to atool for use in handling storage batteries of Vthe type Whichare used in modern automobiles.

The storage batteries now used in automo` biles are enclosed in rectangular boxes presenting flat sides and ends and a fiat top, from which top two cylindrical or slightly coned posts extend a short distance, to provide ends for attaching conductor cables. This assembly will hereinafter be designated as the battery. The present device contemplates a tool which willV engage the projecting posts after the cables have been removed therefrom rby which tool the battery and its enclosing box'may be lifted from the machine. Y

`The objects of the present invention are: To provide a lifting tool whichvvvill engage zo firmly with the battery posts and which when so engaged-willestablish a substantially rigid structure for handling the battery;` e

A further object is to provide a lifting tool which will not' only engage the battery rigidly but which will be rovided with a hand grip through which a vantage may be taken of the rigidity of the connection tothe battery to not only move the battery endvvise and sidewise, and twist it about its vertical axis but which may also be available to bodily'tilt the battery so that the vertical axis may be inclinedto any desired position; A further object is to insulate the tool from the battery posts. Y

Still further objects are to provide in a pair of pliers, loops or grips whereby additional pressure `may be applied' as by engaging the grip, with an additional pair ofpliers, and/or to insulate these grips. y' y -The means by which the foregoing Land other objects are accomplished and the manner of their accomplishment will readily be understood from the following specification on reference to the accompanying drawings, in which o Fig. l is a side elevation of the tool; Fig. 2 is a plan view of the gripping end of thetool taken as on the line II-II of Fig. l, looking down;

50 Fig. 3 1s a perspective view of a battery showing the tool engaging the projecting posts thereof; y

Fig. l is an enlarged fragmentary section taken as on the line IV-IV of Fig. 2 and illustrating one method of insulating the post grips from the handles;

Fig. 5 is a fragmentary view showing a` modified method of connecting the grips to l and insulating them from the handles and Fig. 6 is a section of the saine parts taken on the line Vl-VI of Fig. 5.

Referring now to the drawings, in which the various parts are indicated by numerals, the device comprises essentially a pair of handles 10, 11 connected together at their upper Vend by a pivot 12. Preferably the handles are provided with extensions 13,14 respectively, positioned beyond the pivot points whereby a grip for the handle members may be provided.` In its preferred form these handles and the extensions therefor are the handles and jawsV of a pair of pliers which may be used for loosening the nuts ordinarily used. to holdconductors on the battery posts and also for loosening the battery connections themselves from the posts so that such tool has the essential requisitesv necessary for removing a battery and replacing same.

Pivotally secured to the outer ends of the handles 10 andll are loops or grips 15, 16 each preferably a comparatively thin piece of material having a hole 17, therethrough, this hole being of a diameter to freely engage over,V the posts of the battery with which it is to be used. Forlred arms 18 extend laterally from each of these plates Vand areveach provided with eyes through which a pin 19 may be passed to pivotally secure the loop to the outer end of the handle members, each `of these being provided with an enlarged boss 20 through which the pin is passed. One loop or both loops are preferably insulated from the bosses 20 by bushings 21 of dielectric` material shown. in detail in Fig. 4, so that an electric circuit is not established between the j posts of thebattery by use of the tool.

In Figs. 5 and 6 the outer ends of the han dle members 11 are forked, similarly to the forks `18 of the loop member, and a link 22 of fabric, or other non-conductor of electricity (ifi to form an insulating member is disposed therebetween and pin connected thereto as by the pins 19 and 23. rl`his link may be formed by folding the insulating fabric over bushings 24 which receive the pins 19 and 23, and securing the portion between such bushings together as by stitching 25.

In using the device the aws of the pliers may be utilized in removing nuts to release the conductor cables and also in working these cables loose if they are stuck or the plier jaws may be engaged with a live wire or other part, the engagement being effected by use of the insulated loops or linger grips whereby manipulation of the tool is effected. Such use of the tool is particularly effective in cramped positions which prevent gripping of the handles directly and especially in such places where live wires or parts are to be handled or are encountered. lt particularly lends itself to picking up such parts by suspending the pliers from the linger grips, to reach downward into constricted places. The loops too may be engaged by an additional pair of pliers and the gripping pressure of the jaws be multiplied. After removal of the cables the loops are dropped over the two posts and an upward pull is exerted on the device causing the loops to securely clamp on the posts and providing a firm attachment thereto. The two handles or legs of the tool and the rigidly disposed posts form a triangle which being rigid acts, when the tool is moved to one side or the other in the plane of the handles and posts to tilt the battery so that it may be pulled out at an angle. Additionally the extension of the handles beyond the pivot point provides an elfective hand grip whereby the tool may be inclined to either side and displacement of the battery in such direction be accomplished. It will be seen therefore that this tool provides not only means for attaching to the post but also for a rigid control, which permits maneuvering of the battery in removing it from its position in the car.

It will of course be understood that the details of construction especially as they relate to theinsulation of the grips from the handles may be varied without departing from the spirit of my invention and I therefore wish it distinctly understood that it is not my intention to limit myself tosuch details except as they may hereinafter be set out in any parti cular claim.

Having described my invention, what I claim is 1. A battery lifting tool comprising a pair of pivotally connected handles, each having an enlarged boss transversely disposed at its free end, each of said bosses having a hole therethrough, bushings of dielectric material disposed in said holes, a pair of loop plates one for each of said handles,` each of said plates having a post engaging hole therethrough and a forked extension to receive a handle boss, and said extension having pin receiving holes therethrough, a pin disposed through said extension holes and said bushing and washers of dielectric material between said boss and said extension part.

ln a battery lifting tool, a pair of inelastic handies, pivotally connected adjacent but spaced from one end of said handles, whereby an extension of said handles beyond said pivotal connection is provided; and a pair of loops, each comprising a flat member of inelastic material disposed at right angles to the plane of said handles, said flat members each having a post engaging hole therethrough, and being pivotally connected, each at the longer end of a handle and means for insulating at least one of said loops from its handle, said pivotall connections constraining said parts, to pivotal movement only around the centers of movement thereof, whereby a rigid structure is accomplished when said tool is engaged for lifting, and controlled movement of the device being lifted is accomplished.

3. In a lifting tool, a pair of inelastic handles, a pivot pin connecting said handles adjacent but spaced from one end of each of said handles whereby an extension of said handles beyond said pivot point is provided; and a pair of loops each comprising a flat member of inelastic material disposed at right angles to the plane of said handles, said Hat members each having a part engaging hole therethrough, and said loops being pivotally connected each at the longer end of a handle, said pivot pins being parallel and constraining said parts to pivotal movement only around said pins, whereby said tool is effective for lifting and controlling movement of the part being lifted.

4. In a lifting tool, a pair of pivotally connected inelastic handles, a pair of loops, each pivotally connected to an end of a handle, each of said loops comprising an inelastic member having a post engaging hole therethrough and which hole is offset from said pivot point, all of said pivots being parallel, and constraining movement of the parts parallel to a single plane, whereby a structure is set up for solidly engaging an article having projectingspaced posts, and controlling the movement of such article.

5. In a battery lifting tool, a pair of inelastic handles pivotally connected for constrained pivotal movement a pair of inelastic loop plates, having each a hole therethrough, adapted to engage over a battery post and pivotally connected each to one of said handles, for constrained pivotal movement relative thereto, at least one of said loops being insulated from its handle, said handles eX- tending from the grip plate pivots past said handle pivot, whereby a grip is formed for lll! ieu

ontrollng movement of said tool, and said tool may be engaged with the posts of a battery and be effective for lifting and controlling movement of the battery.

In testimony whereof I hereunto affix my signature.

GEORGE F. ooLLEY.
